What is the length of side bc of the triangle? enter your answer in the box.

The triangle is an equiangular triangle so that means it must be an equilateral triangle.

3x - 3 = x + 8

2x = 11

x = 5.5

BC = 3(5.5) - 3

BC = 13.5

47 - 90 = 43

43 - 180 = x

x = 137

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
